所以我有一个带有cocoon gem的Rails 4应用程序，带有2个单选按钮。如果用户选择是单选按钮，则显示div＃kites部分并且＆＃34;添加风筝＆＃34;应该点击。我知道代码进入if语句，因为当我选择Yes单选按钮时，＆＃34; hello kite＆＃34;显示在控制台中，显示div＃kites部分。但是，没有点击链接。我可以在控制台中输入 $（＆＃34; #kites＆gt; div.links＆gt; a＆＃34;）。触发器（＆＃34;点击＆＃34;）并触发适当的行为。关于为什么它可以在控制台中工作而在代码中没有的任何想法？
Coffeescript代码：
$("input[name=led_to_kite]").change ->
if($("#led_to_kite_Yes").is(":checked"))
$("#kites").show()
$("#kites > div.links > a").trigger("click")
console.log "hello kite"
